Japan’s Nuclear Share Could Exceed 40 Percent By 2030, Says Report

Nuclear energy will be a key power source in Japan,
accounting for more than 40% of total electrical energy generation in the
country by 2030, a report says.

The Institute of Energy Economics of Japan’s (IEEJ) latest energy supply and
demand outlook says the nuclear share will increase from approximately 29% in
2005 to 41% in 2030.

Nuclear generating capacity is likely to increase to 62.86 gigawatts (GW) in
2030, up from 47.59 GW at the end of 2005.

The report says seven new nuclear units are expected to come online between
2006 and 2020, with three more between 2020 and 2030.

The Japan Atomic Industrial Forum said the IEEJ is calling for existing
plants to be operated for 60 years, with measures taken to improve aging
reactors. Only one decommissioning is expected before 2030 – Japan Atomic
Power Company’s Tsuruga-1, a 341-megawatt boiling water reactor that began
commercial operation in 1970.

The IEEJ report says capacity factors of the country’s nuclear units are
expected to improve to around 88%, largely as the result of extending the
intervals between periodic inspections.

Electricity consumption will increase by 0.9% a year, although total energy
consumption in 2030 will be 10% below the 2004 level. Thirty percent of final
energy consumption in 2030 is expected to be electricity.

In March 2005, Japan’s Agency for Natural Resources and Energy, part of the
Ministry of Economy, Trade and Industry, published a package of
recommendations for nuclear energy policy beyond 2030 that included calls for
existing light water reactor units to be used for at least 60 years and for a
gradual introduction of fast breeder reactors by the middle of the century.

Japan has 55 nuclear units in commercial operation. One unit, the
246-megawatt (MW) Monju fast breeder unit, is in “long-term shut-down”.
Another, the 866 MW pressurised water reactor unit Tomari-3 in the northern
prefecture of Hokkaido, is under construction.
